PEN.

' $PECIFIGATION forming part of Letters Patent No. 699,464, dated May 6, 1902.

Application filed March 3, 1902- To aZZ 2071,0112, it may concern:

Be it known that I, FREDERICK J. W.- FISCHER, a citizen of the United States, and a resident of Rockaway, in the county of Queens and State of New York, have invented a new and useful Improvement in Pens, of which the following is a specification.

It is the object of my invention to improve the action of a steel pen and to makeit sensitive and freely responsive to pressure. This result I produce by subjecting it to a grinding action by which the pen-nib is reduced in thickness upon its longitudinal median line from the piercing along and on both sides of the longitudinal slit which leads from the piercing to the point.

I will first describe the improvement by reference to the accompanying drawings, forming part of this specification, and will then point out more particularly in the claimwhat I believe to be new and of my own invention.

In the drawings,'Figure 1 is a view, on an enlarged scale, of apen embodying my invention. Fig. 2 is a longitudinal central section of the same. Fig. 3is a cross-section on line 3 3, Fig. 1. Fig. 4 is a view of apen in which the Hat central reduced surface is of less length than that shown in Figs. 1 to 3. Fig. 5 is is a front elevation, and Fig. G is a side elevation, of a mechanism for producing the fiat surface on the pen.

In the drawings, A is a steel pen having a piercing at and a central longitudinal slit Z) from the piercing to the point. The pen thus far is of ordinary construction. WVhat there is novel in it is the flat ground or reduced surface 0, which borders the central longitudinal slit 1), as well as both sides of the piercing a, and extends from the piercing nearly to the pen-point. By varying the length of the fiat ground surface c-that is to say, the distance it extends from the piercing a toward the point, the flexibility of the pen will Serial No. 96,484. (No model.)

be varied. As, for example, a pen having a flat ground or reduced surface a of the dimensions shown in Fig. 4 will have less flexibility than one provided with the relatively more extensive flat ground-surface shown in Fig. 1.

A convenient and expeditious way of forming the fiat reduced surface 0 on the pen is to place the pen, concave face down, upon a .rest 1", formed to receive it and supported upon a stand 3, movable in the direction of the length of the pen, under a power-driven rapidly-revolving emery-wheel WV, having a flat cylindrical periphery, the stand 3 or rest 1' being vertically adjustable also, so as to vary the extent of grinding action. This brief description of mechanism is here given only to indicate to those skilled in the art not merely how the fiat reduced surfacecan be produced, but also the form and character of the reduction itself. A pen thus made possesses an ease and flexibility of action and a responsiveness to pressure which is not found in the ordinary pen. It has, indeed, the socalled quill action, an action which cannot be produced by present methods of grinding and which, so far as I am aware, is not found in any steel pen to-day in the market.

Having described my improvement, what I claim herein as new, and desire to secure by Letters Patent, is

As a new manufacture a steel pen having the longitudinal central flat reduced surface 0, extending from the piercing along and on both sides of the central slit leading from the piercing to the point, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 28th day of February, 1902.
